Abstract

Abstract : Manufacturing fine metal mask (FMM) is the biggest hurdle to realize UHD grade AMOLED pixels for smartphone applications and even higher resolutions such as virtual reality displays. We have developed 800ppi or more grade fine metal mask processing system via femtosecond laser with unique thermal damage free process. Thanks to the unique processing strategy, without sacrificing the processing speed, UHD grade FMM is realized for AMOLED mobile displays.
